Stocks ended Monday mixed in London while oil prices pushed higher as investors weighed political developments in the UK and the lack of progress in peace talks between the US and Iran.

The FTSE 100 closed up 36.36 points, 0.4%, at 10,269.43. The FTSE 250 ended down 41.52 points, 0.2%, at 22,807.86, and the AIM All-Share rose 7.98 points, 1.0%, at 822.41.

Brent crude for July delivery was trading at 103.70 US dollars a barrel on Monday, up compared to 101.49 dollars at the time of the equities close in London on Friday.

The continued stalemate between the US and Iran dashed investors’ hopes of an imminent peace deal and heightened concerns over further violence and disruptions to oil supplies through the Strait of Hormuz.

US President Donald Trump described Tehran’s response to the latest US outline for peace talks as “totally unacceptable” in a social media post.

Iran said it had demanded the release of its frozen assets and the end of a US blockade of its ports.

“The price of oil remains highly reactive to news around the reopening of the Strait of Hormuz, both positive and negative,” said Kathleen Brooks, research director at trading group XTB.

“Signs that tankers are getting through the Strait, even if it is a trickle, could weigh on the oil price in the coming days,” she added.

But JPMorgan analyst Natasha Kaneva thinks that oil prices could remain a little over 100 dollars for most of the rest of this year, averaging 97 dollars for 2026 as a whole, in a scenario assuming the Strait of Hormuz reopens on June 1.

“Even if the Strait reopens in June, the seasonal lift in summer demand, combined with the exceptionally large commercial stock draws seen in March and April, and likely again in May, should push OECD inventories toward operational stress levels by August.

“This is what keeps crude prices elevated in the low 100s (US dollars) through most of the year, rather than allowing a sharp retracement once Hormuz reopens, Ms Kaneva wrote in a research note.

In Europe on Monday, the CAC 40 in Paris ended down 0.7%, and the DAX 40 in Frankfurt edged up 0.1%.

In New York, the Dow Jones Industrial Average was up 0.1%, the S&P 500 rose 0.3% while the Nasdaq Composite was up 0.2%.

The yield on the US 10-year Treasury widened to 4.39% on Monday from 4.37% on Friday. The yield on the US 30-year Treasury stretched to 4.97% from 4.94%.

The pound firmed to 1.3651 US dollars on Monday afternoon from 1.3623 dollars on Friday. Against the euro, sterling was higher at 1.1584 euros from 1.1568 euros on Friday.

In London, bond yields crept higher, with domestic political uncertainty adding to the Middle East worry.
